584. Commandment – It does not behove a believer to kill a believer unless it be by mistake
[4:93] It does not behove a believer to kill a believer unless it be by mistake. And he who kills a believer by mistake shall free a believing slave, and pay blood money to be handed over to his heirs, unless they remit it as charity. But if the person slain be of a people hostile to you, and be a believer, then the offender shall free a believing slave; and if he be of a people between whom and you is a pact, then the offender shall pay blood money to be handed over to his heirs, and free a believing slave. But whoso finds not one, then he shall fast for two consecutive months — a mercy from Allah. And Allah is All-Knowing, Wise. [4:94] And whoso kills a believer intentionally, his reward shall be Hell wherein he shall abide. And Allah will be wroth with him and will curse him and will prepare for him a great punishment.
[7:87] ‘And sit not on every path, threatening and turning away from the path of Allah those who believe in Him, and seeking to make it crooked. And remember when you were few and He multiplied you. And behold, what was the end of those who created disorder!
[5:34] The reward of those who wage war against Allah and His Messenger and strive to create disorder in the land is only this that they be slain or crucified or their hands and their feet be cut off on alternate sides, or they be expelled from the land. That shall be a disgrace for them in this world, and in the Hereafter they shall have a great punishment;
